So this is my first season hunting and my first time really in archery with the compound bow. I currently have the PSE Beast EXT and its set to a 33" draw length. Initially the shop where I bought it set me up at 56# but showed me how to crank it up to the full 70#. I have a few questions that I was hoping someone could help me with: Beside stroking my ego, and having an arrow that flies slightly straighter is there any reason to have my bow at the 70# instead of at the 56 that the shop set me up with (the bows range is 56-70)? Just playing around with it I currently have it at ~67# And my second question is, I am currently using the Victory Vforce Sport 350 arrows (uncut). Is there a hunting reason to get a heavier arrow or lighter arrow, or should I just stick with the 350's. I am also undecided on mechanical vs broadhead, I just worry about having enough KE for an ethical shot with the mechanical. Thanks guys, I appreciate any and all help!
